The invention discloses a Kui-type bicycle which comprises a bicycle frame and an axle rotatably connected with the bicycle frame, the axle is sleeved with a volute spiral spring, the bicycle frame is provided with a fulcrum, the fulcrum is rotatably connected with a lever, the lever is divided into a first section and a second section by the fulcrum, and the end of the second section is connected with the output end of the volute spiral spring; during use, a user directly acts acting force on the volute spiral spring through the lever, the volute spiral spring is pulled, the volute spiral spring elastically deforms and drives the wheel shaft to rotate at the same time, and therefore the wheel is driven to rotate, and after the wheel reaches the preset position, the volute spiral spring returns, the lever is driven to return to the original position, and the next circulation is conducted. Sin the process of energy transmission is reduced, the purpose of reducing energy loss in power transmission is achieved.
本发明公开奎式脚踏车,包括车架和与车架转动连接的轮轴,所述轮轴上套设有涡卷弹簧,所述车架上设置有支点,所述支点上转动连接有杠杆,所述杠杆被所述支点划分为第一段和第二段,所述第二段端部与所述涡卷弹簧输出端连接;使用时,使用者直接通过杠杆将作用力作用在涡卷弹簧上,通过拉动涡卷弹簧,涡卷弹簧发生弹性形变的同时,带动轮轴转动,从而带动车轮转动,达到预设位置后涡卷弹簧回复,带动杠杆回复原位,进行下一次循环,由于减少能量传递的过程,从而达到在动力传递中减少能量损失的目的。
